6-7mm. This is the first of a sequence of small, rather satiny white and grey
species with similar facies to the marshalli sequence but much weaker
marking and transverse shading, the latter tending to be restricted to the
costal zone. Like the
marshalli
sequence, they can only be identified reliably from characters of the male
genitalia. In chamberlaini the valves are distally rather broad, slightly
falcate where the costa reaches the distinctly acute apex. The harpe is robust,
acute, flexed at right angles and slightly more distal than in the previous
group. The aedeagus has a slender, reflexed hook apically, and the vesica
contains a loose group of slightly curved spines. The species appears to be
close to M. javanica van Eecke stat. & comb. n. (Java; the taxon
vicina
Roepke (Sumatra) may also be related, but is based on a single female), having
similar ornamentation to the aedeagus and vesica (lacking in the Himalayan
melanota
of which javanica
was originally described as a subspecies). The vesica is longer and narrower in
javanica, with the spines more closely associated in a terminal clump.
Also related is the Nepalese M.
subfuscataria Inoue
(1998) comb. n., where the harpe and apical part of the valve are
more strongly curved.
